Description

The present invention relates to a first agent composition for hair dyeing. More specifically, the present invention relates to a first agent composition for hair dyeing, which has good hair dyeability and is excellent in long-term stability at high temperature and stability over time at high temperature.

Due to the growing awareness of fashion in recent years, hair coloring agents that can easily change the color of hair have been accepted by many people regardless of gender. There are various types of hair coloring agents such as permanent hair dyes, semi-permanent hair dyes, bleaching agents, and temporary coloring agents, and they are used according to their needs. Among them, the permanent hair dye has an excellent long-lasting hair dyeing effect, and because of this property, it is the hair coloring agent currently used by most people.

As a permanent hair dye, a two-agent type consisting of a first agent composition for hair dyeing containing an oxidizing dye and an alkaline agent and a second agent composition for hair dyeing containing an oxidizing agent such as hydrogen peroxide is widely used. It's being used. The alkaline agent contained in the first agent composition for hair dyeing is an indispensable component for bleaching and dyeing, but it may cause a decrease in feel such as squeaky hair.

Therefore, the first agent composition for hair dyeing contains oily components such as hydrocarbons, higher alcohols and silicone oils in order to improve the feel of hair. These oily components are present as an emulsion in the first agent composition for hair dyeing by being contained together with an emulsifier such as a surfactant. However, since the first agent composition for hair dyeing contains an oxidative dye, the stability over time tends to be lower than that of a general emulsion. In addition, it may be placed in a harsh environment during transportation and storage, and especially in the summer, it may reach about 60 ° C in the container used for transportation overseas due to the influence of temperature and reflected heat. Yes, in such a high temperature environment, coalescence and creaming are promoted and separation is likely to occur.

Various attempts have been made to solve these problems. For example, Patent Document 1 below contains an anionic surfactant and a polyhydric alcohol for the purpose of improving the stability and feel of the hair dye composition, and substantially nonionic surfactant and cationic surfactant. A hair dye composition containing no agent and amphoteric surfactant is disclosed.

Patent Document 2 below discloses a hair dye composition containing an alkanolamine, a higher alcohol, and a quaternary ammonium-type cationic surfactant for the purpose of improving hair dyeability and feel.

The following Patent Document 3 describes a first agent composition for hair dyeing containing a silicone oil, a higher alcohol, a nonionic surfactant, a cationic surfactant, a higher fatty acid, and water for the purpose of high temperature stability and improvement of feel. Is disclosed.

Japanese Unexamined Patent Publication No. 2003-171247 Japanese Unexamined Patent Publication No. 2004-189717 Japanese Unexamined Patent Publication No. 2016-121104

The first agent composition for hair dyeing of Patent Document 1 contains an anionic surfactant and a polyhydric alcohol such as glycerin or propylene glycol to improve stability over time at high temperatures. However, the polyhydric alcohol may inhibit the penetration of the dye into the hair and reduce the hair dyeing effect.

The first agent composition for hair dyeing of Patent Document 2 is good by using alkanolamine as an alkaline agent and setting the ratio of the higher alcohol to the quaternary ammonium type cationic surfactant within a specific range. Although the hair dyeing effect and the improvement of the hair feel were achieved, the stability over time by the hair dye containing silicone oil at high temperature is not disclosed.

The first agent composition for hair dyeing of Patent Document 3 contains silicone oil, higher alcohol, nonionic surfactant, cationic surfactant, higher fatty acid and water to improve stability over time at high temperature. Achieves improved hair feel after treatment. However, when a higher fatty acid is contained, an odor derived from the fatty acid is generated over time, and there is a tendency that the user feels an unfavorable odor when using the fatty acid.

Therefore, the present invention has been made in view of the above problems, and is a first agent composition for hair dyeing, which has good hair dyeability and is excellent in long-term stability at high temperature and stability over time at high temperature. The purpose is to provide.

The present inventors impose a solid higher alcohol, a nonionic surfactant and a cationic surfactant at 25 ° C. in the first agent composition for hair dyeing, and solid higher alcohol and nonionic surfactant at 25 ° C. We have found that the above problems can be solved by adjusting the content ratio of the agent and the cationic surfactant, and the content ratio of the nonionic surfactant and the cationic surfactant within a specific range, and have completed the present invention. rice field.
